l'amas d'Hercule: Comportant plus de 500 000 étoiles, il est aussi l'un des plus vieux objets : son âge est estimé à 12 ou 14 milliards d'années. situé à environs 25 000 années lumières de la Terre, il a, pour l'anecdote, était la cible d'un message envoyé dans l'espace comportant des indications sur notre planète en quête de vie extraterrestre (si toute fois un réponse nous parvenait d'une planète proche d'une des étoiles de cet amas, dans 50 000 ans: le temps d'un aller/retour à la vitesse de la lumière :) ).

A group of Wheaton Academy students put together a detailed diorama of the allied landings in France on D-Day.
Cantigny Park in Wheaton commemorated the 70th anniversary of the D-Day landings with vehicles, reenactors and a series of engaging activities so that young people could learn the history in engaging ways. As a special treat, there were veterans of the beach landings who were there to share their experiences and answer questions.

Hercules Globular Cluster. 139x20' (38min) exposures, captured in the beginning twilight and in the full moon. Tough conditions but it turned out alright.

Hurray, I got my scope drift aligned for the first time! 14 x 30 secs at ISO 800, UV'IR block filter, f7.5.
M13 in Hercules, still needs work but a starting point!
M13 Globular Cluster-2012.09.07-Canon EOS450D-300mm Lens-120sec-ISO 1600-single exposure-Gimp2.6-Neat Image. This globular cluster is located in the constellation of Hercules.
The M13 (or NGC 6205) in the Hercules sign. A well known sight on the North sky. It was discovered by Edmond Halley, in 1714.

New camera, who 'dis? A first short test with my new QHY268M on M13. I used the full well 2CMS mode for this one thinking that the additional depth would help prevent saturating stars. I guess it worked a little, but I think photographic mode adds less noise, and I'll be trying that next. As usual my flat frame game is lame. :( I took flats and flat darks, but the flats just make everything look worse. I think this one is obvious though as I was messing with a lot of settings and I think there were changes between taking the lights and the flats. Still, PixInsight did a great job with the gradients and there wasn't a lot of dust to begin with...

M13 was discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764.
The Arecibo message of 1974, designed to communicate the existence of human life to hypothetical extraterrestrials, was transmitted toward M13. The reason was that with a higher star density, the chances of a life harboring planet with intelligent life forms, were higher. Even though the message was transmitted, M13 will no longer be in that location when it arrives.
